Description

Technical Field

[0001] The utility model relates to the technical field of double-roll rubber mixing, in particular to a double-roll rubber mixer for producing rubber sealing rings. Background Technique

[0002] The double-roll rubber mixer is also known as an open mill, which mixes the raw materials used to make rubber and uses two groups of rollers that can be heated by steam for stretching. At the same time, the user also needs to continuously stretch and cut during the mixing process, so that the raw materials are strongly extruded between the two rollers, so as to achieve the purpose of increasing the rubber plasticity;

[0003] Since different rubbers are used in different environments, the rubber rings used in aviation are generally used to increase the sealing performance of aviation parts. The rubber sealing performance is greatly related to the tensile strength of the rubber. During the stretching process of the rubber, a certain dose of softening agent and filler can be added to increase the tensile strength. However, excessive doses of the softening agent and filler will reduce the tensile strength of the rubber. Therefore, during the mixing process, it is necessary to quickly move the rubber and the softening agent to mix quickly, and at the same time accelerate the stretching and extrusion, so that the rubber product can resist the ultimate ability of tensile failure;

[0004] During the mixing process, the rubber needs to gather towards the middle and then be stretched at regular intervals. However, due to the large amount of rubber and the fact that one side of the roller is movable, there is no corresponding mechanism above the mixer to assist the user to gather the rubber in time for mixing, so that after the user adds the softening agent and filler, they cannot mix the softening agent and filler with the rubber in time, resulting in a higher content of the softening agent and filler in a certain part of the rubber product, affecting the tensile strength of the rubber.

[0005] In view of the above situation, we propose a double-roll rubber mixer for producing rubber sealing rings. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a double-roll rubber mixer for producing rubber sealing rings.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A two-roll rubber mixer for rubber sealing ring production, including an open mill workbench. An inner wall above the open mill workbench is rotatably connected with a fixed roll. The inner wall of the open mill workbench, which includes the open mill workbench, is penetrated and provided with a chute. A slider is slidably connected inside the chute. An inner wall of the slider is rotatably connected with a movable roll. One side of the slider away from the fixed roll is rotatably connected with a first adjusting screw rod. The first adjusting screw rod penetrates the open mill workbench and is threadedly connected with the open mill workbench. An inner wall of the open mill workbench is rotatably connected with a bidirectional screw rod obliquely above the movable roll. The bidirectional screw rod penetrates and is threadedly connected with a moving ring. A fixed frame is fixedly connected to an outer surface below the moving ring. A plug rod is slidably connected inside the fixed frame. One end of the plug rod is rotatably connected with a universal rod. One end of the universal rod away from the plug rod is fixedly connected with an aggregation ring.

[0009] One end of the plug rod close to the fixed frame is internally threadedly connected with a second adjusting screw rod. The second adjusting screw rod penetrates the fixed frame and is rotatably connected with the inside of the fixed frame.

[0010] The plug rod and the universal rod are connected through a spherical bearing.

[0011] An outer surface of the open mill workbench is fixedly connected with a third driving motor. An output end of the third driving motor is fixedly connected to one end of the bidirectional screw rod.

[0012] Preferably, a sliding frame is fixedly connected to an outer surface of the open mill workbench close to the third driving motor. A slidable second driving motor is arranged above the sliding frame. A bottom of the second driving motor is fixedly connected with a bracket. A pulley is fixedly connected below the bracket. The pulley is slidably connected inside the sliding frame.

[0013] Preferably, an output end of the second driving motor is fixedly connected to one end of the movable roll close to the third driving motor. A connection part between the second driving motor and the movable roll penetrates the slider.

[0014] Preferably, a first driving motor is fixedly connected to an outer surface of the open mill workbench away from the third driving motor. An output end of the first driving motor is fixedly connected to one end of the fixed roll away from the third driving motor.

[0015] Preferably, a debris collection trough is slidably connected directly below the fixed roll and the movable roll on the open mill workbench. A control console is fixedly connected to an outer surface of the open mill workbench close to the first driving motor. A fixed rod fixedly connected to an inner wall of the open mill workbench is arranged directly above a gap between the fixed roll and the movable roll.

[0016] A two-roll rubber mixer for the production of rubber sealing rings proposed by the present utility model has the beneficial effects that when softeners and fillers are put in, the user starts the third driving motor to drive the bidirectional lead screw to drive the moving rings on both sides to move inwards, driving the rubber to move inwards, making the rubber gather towards the midpoint, facilitating the fixed roller and the movable roller to stretch the rubber. At the same time, the rubber on both sides gathers towards the direction where softeners and fillers are sprinkled, enabling the softeners and fillers to quickly and fully blend with the rubber, preventing the content of softeners and fillers in a certain part of the rubber from being too high and affecting the tensile strength of the rubber. When the movable roller moves, the user can rotate the second adjusting screw to drive the inserting rod to slide inside the fixed frame, so that the gathering ring can fully fit on the surface of the movable roller, facilitating the gathering ring to gather the rubber on both sides inwards, and thus facilitating the rubber mixer to open and refine the rubber.

A debris collection trough 3 is slidably connected to the open mill workbench 1 directly below the fixed roll 5 and the adjustable roll 4. A control console 2 is fixedly connected to the outer surface of the open mill workbench 1 near the first drive motor 7. A fixed rod 6 fixedly connected to the inner wall of the open mill workbench 1 is provided directly above the gap between the fixed roll 5 and the adjustable roll 4. A sliding frame 14 is fixedly connected to the outer surface of the open mill workbench 1 near the third drive motor 22. A slidable second drive motor 11 is provided above the sliding frame 14. The bottom of the second drive motor 11 is fixedly connected to a support 12. A pulley 13 is fixedly connected below the support 12. The pulley 13 is slidably connected inside the sliding frame 14. The output end of the second drive motor 11 is fixedly connected to one end of the adjustable roll 4 near the third drive motor 22. The connection between the second drive motor 11 and the adjustable roll 4 penetrates the slider 9. A first drive motor 7 is fixedly connected to the outer surface of the open mill workbench 1 away from the third drive motor 22. The output end of the first drive motor 7 is fixedly connected to one end of the fixed roll 5 away from the third drive motor 22. Rotating the first adjusting screw 10 drives the slider 9 to move, thereby driving the adjustable roll 4 to move. At the same time, the user pushes the second drive motor 11 to move. Starting the second drive motor 11 can drive the adjustable roll 4 to rotate.

[0024] A two-way lead screw 15 is rotatably connected to the inner wall of the open mill workbench 1 obliquely above the adjustable roll 4. The two-way lead screw 15 is threadedly connected to a moving ring 16. A fixed frame 17 is fixedly connected to the outer surface below the moving ring 16. A plug rod 18 is slidably connected inside the fixed frame 17. A universal rod 19 is rotatably connected to the bottom of the plug rod 18.

The output end of the third drive motor 22 is fixedly connected to one end of the two-way lead screw 15. Starting the third drive motor 22 drives the two-way lead screw 15 to rotate, thereby driving the two converging rings 20 on both sides to move in different directions.

[0025] In summary: During the application of the present utility model, during open milling, the user puts the raw materials between the fixed roller 5 and the movable roller 4, and simultaneously starts the first drive motor 7 and the second drive motor 11 to drive the fixed roller 5 and the movable roller 4 to rotate at different speeds respectively, so as to achieve the purpose of extruding the rubber raw materials. During the open milling process, the user needs to add softeners and fillers according to the state of rubber open milling. After adding the softeners and fillers, the user can first cut the open-milled rubber and then stretch and open mill it. Since the softeners and fillers are in powder form, both the rubber and the softeners and fillers are solids. Therefore, in order to ensure that the softeners and fillers can quickly blend with the rubber, the user can squeeze the rubber inward and push it together, that is, start the third drive motor 22 to drive the bidirectional lead screw 15 to drive the moving rings 16 on both sides to move inward, driving the rubber to move inward, so that the rubber gathers towards the midpoint, facilitating the fixed roller 5 and the movable roller 4 to stretch the rubber. At the same time, it makes the rubber on both sides gather towards the direction where the softeners and fillers are sprinkled, enabling the softeners and fillers to quickly and fully blend with the rubber, preventing the high content of softeners and fillers in a certain part of the rubber from affecting the tensile strength of the rubber. At the same time, when the movable roller 4 moves, the user can rotate the second adjusting screw 21 to drive the insertion rod 18 to slide inside the fixed frame 17, so that the gathering ring 20 can fully fit on the surface of the movable roller 4, facilitating the gathering ring 20 to gather the rubber on both sides inward.
